Patent EP-0367497-A2 (EP)
Inventor: BURNS GARY THOMAS
IPC: C08G79/00
Filed: 1989-10-26
Abstract: A process for the preparation of preceramic metallopolysilanes is described. The process consists of reacting polysilanes with metallic compounds from which can be generated open coordination sites associated with the metallic element. Such open coordination sites can be generated by the reduction of the metallic compound with an alkali metal reducing agent or by heating a metallic compound which has thermally labile ligands or by the UV irradiation of a carbonyl-containing metallic compound. The metals which can be incorporated into the polysilane include aluminum, boron, chromium, molybdenum, tungsten, titanium, zirconium, hafnium, vanadium, niobium and tantalum. These metallopolysilanes are useful, when fired at high temperatures, to form metal-containing ceramic materials.

Abstract: In a semiconductor memory device having a sense amplifier (22) for amplifying a potential difference between a pair of regular bit lines (11,  11 ), the memory device further comprises a dummy bit line (41) having a load capacitance equal to that of each of the pair of regular bit lines, a dummy memory cell (42) having a bit line drive capability equal to that of the regular memory cell (14), a precharging circuit (43) for precharging the dummy bit line, a selecting circuit for simultaneously selecting the regular memory cell and the dummy memory cell, a dummy bit line potential sensing circuit (50) for sensing that the potential of the dummy bit line is changed from a precharge potential by a predetermined potential when the dummy memory cell is selected by the selecting circuit, and a sense amplifier control circuit (51, 49, 52) for receiving an enable signal which enables operation of the sense amplifier, and a sensed signal from the dummy bit line potential sensing circuit, to determine an operation period of the sense amplifier, in response to both the enable and the sensed signals. When the output data is determined by the sense amplifier, an output logic level of the level sensor is inverted, and the sense amplifier is disabled. The sense amplifier is kept disabled until the next clock signal is generated, and no feedthrough current flows during this period, decreasing wasteful power cur­rent consumption.

Abstract: The invention relates to a method and a device for the disposal of building materials contaminated with harmful substances, such as asbestos and applied in the interior space of buildings to parts of the same, for example sprayed asbestos. Here, the interior space of the building is hermetically sealed off from the exterior space and put under vacuum. The building materials (64) contaminated with harmful substances are then separated piece by piece from the building parts, and the rubble (70) forming as a result is mixed with a binding agent, if need be after previous comminution, in a mixing container (12) while forming a viscous mixture (58). After being sealed off from the interior space (20), the mixing container (12) is opened to the exterior space, where the viscous mixture (58) is hardened to form transportable blocks after the mixing container (12) is emptied. According to the invention, the mixing container (12) enclosed in the interior space (20) is filled with the rubble (70) from the interior space (20) under the pressure prevailing there or under the pressure additionally lowered relative to this interior space (20) and is then sealed off from the interior space (20) and compressed air is applied to it during and/or after formation of the viscous mixture (58), the latter being conveyed for hardening into the exterior space under the action of the compressed air via a conveying line (22) connecting the mixing container (12) to the exterior space. <IMAGE>

The new switching device 1 has at least one switch 2, which can be actuated magnetically and is arranged inside a vehicle, in the circuit for the respective element or set or the like and an actuating magnet 3, allocated specifically to this switch 2. A switch which can be actuated manually, for example with the aid of a key, is hence dispensed with and at least one switch, which can be actuated magnetically, is provided instead, which is arranged, for example, directly behind a glass window pane, e.g. of a vehicle door, and can be set in or out of operation at will from the exterior by means of an associated actuating magnet. Application: e.g. door lock deicing systems in which it is intended to switch on a heating resistor for a short time. <IMAGE>

Abstract: A pseudo two-port "snoopy" cache architecture is provided with an associative cache memory and a directory. The cache memory incorporates read/modify/write capability wherein read and write operations may be performed within a single memory cycle. The cache controls include a line state array memory having a plurality of state bits for each entry in the cache directory and is provided with addressing means whereby whenever the directory is accessed, a corresponding state pattern will be accessed in the line state array. The cache-memory also includes with a reload buffer for writing data into the cache and a store back buffer for writing data from the cache into the main memory. The controls for the cache directory execute two complete directory cycles within the time it takes to execute a single cache memory access. "Snooping" operations are performed against the system during alternate directory cycles and CPU access operations are performed during intervening cycles. The cache memory controls effect read/write operations in said cache contingent upon the current state of "state bits" in an accessed line of the line state array memory and selectively modify the state bits if necessary. The memory controls prevent data in the store back buffer from ever becoming dirty by loading said store back buffer in a single cache memory cycle immediately thereafter obtaining control of said memory bus and storing said data back to main memory before any other "bus master" can obtain control of said bus. The controls further include procedures for accessing a "dirty" bit in the state array at an address of a to-be-replaced line in the cache when the reload buffer is full and ready to write data into the cache. The dirty bit indicates if a store-back operation is necessary.

Abstract: 2.1. The invention relates to a receiver for time-varying distorted data signals, with an equaliser, a channel estimator which, with the aid of a training signal transmitted along with the data signals and a replica of the training signal stored in the receiver, generates a channel information signal which it feeds to the equaliser, and with an arrangement for channel tracking which, with the aid of data detected by the equaliser, generates correction values for the channel information signal. With very high relative speeds between the transmitter and the receiver (e.g. 200 km/h during operation of the mobile radio unit, for example in a vehicle), this can nevertheless result in a deterioration in the bit error rate. …<??>2.2. This is prevented in the case of the present invention by supplying to the channel tracking arrangement, following transfer of the channel information determined from the training signal, a part at least or all of the received training signal prior to the data signals which are to be equalised and detected. …<??>2.3.

Abstract: A sensor and method are described which use light diffracted from diffracting elements (20) having at least one region of nonuniformity. The sensor is useful for monitoring displacement, stress, temperature and pressure. The diffraction grating (20) is fabricated from first and second gratings (22,24) and has a step-wise change in the grating period at an inter-grating boundary (26). The grating is illuminated with broadband light from a source (12) which is diffracted as a function of the irradiated position on the grating with the wavelength of the diffracted light and the change in wavelength is a function of the diffraction grating position. In another form of the present invention, a diffraction grating is provided with a variable grating period which can vary linearly, exponentially, or in accordance with some other function, the wavelength of the diffracted light being a function of the relative displacement of the grating. Additionally, gratings can be combined to provide a transducer that provides an output that can be compensated for temperature variations.
